But Trump’s popularity comes at a time when his heightened rhetoric also seems to be scaring a large number of American voters. The Times/CBS poll found that nearly two-thirds of Americans are either concerned or frightened over the prospect of a Trump presidency (including one-third of Republicans surveyed).

A Trump campaign spokesperson did not immediately respond to Fortune’s request for comment on the poll.

The poll also found that more than half of the surveyed voters are either concerned or scared about the prospect of Democratic frontrunner Hillary Clinton occupying the White House. According to the poll, Clinton continues to enjoy a 20-point lead over Vermont Senator Bernie Sanders.

With the first primary votes still more than seven weeks away, it’s still early in election cycle, and many voters have yet to make up their minds. The poll found that more than half of Democrats have already decided on a candidate to back in next year’s election, but 64% of Republicans remain unsure.
